Now, scientists say they recently developed innovative 4D-printing methods that involve 3D-printing items that are designed to change shape after they are printed.

By using 4D printing and their model, they are instead able to reverse engineer the needed properties of the object to attain its final shape.

Here comes 4D: Shape-shifting objects that fold themselves up and change over time are created using a printer The technique uses a 'hydrogel ink' that swells when it is added to water ...

Using a new technique known as 4D printing, researchers can print out dynamic 3D structures capable of changing their shapes over time.

4D printing is the process of using 3D printing to create objects that can change their shape or properties in response to environmental factors such as light and temperature.

This week, scientists from Harvard University unveiled a new 4D printing process that creates objects capable of changing shape when submerged in water.

Thanks to the innovative marriage of 3D printing and smart materials that 4D-printed objects are able to change shape and property when they are triggered by temperature or other environmental ...

Originally, “4D printing” referred to 3D printed objects that used “smart materials” that could then self-assemble. Now, the term covers 3D printed objects that can change shape and ...

By mimicking the way orchids, calla lilies and other plants bend and twist, scientists have created shape-shifting "4D-printed" structures that they say could one day help heal wounds and be used ...
